Part (i)
Answer: m/n
--------------------
Explanation:
You divide the total bill over the number of people at the dinner. This leads to the quotient and the amount each person pays (each person pays the same amount).
====================================================
Part (ii)
Answer: 80 dollars
--------------------
Explanation:
Plug in m = 400 and n = 5 to get
m/n = 400/5 = 80
====================================================
Part (iii)
Answer: m = 7x
--------------------
Explanation:
x = m/n
x = m/7
7x = m ... multiply both sides by 7
m = 7x
The total bill is 7 times of what each person paid.
====================================================
Part (iv)
Answer: 7 people
--------------------
Explanation:
x = 20 is the amount each person paid
m = 140 is the total bill
n = number of people who went to dinner
x = m/n
20 = 140/n
20n = 140 ..... multiply both sides by n
n = 140/20 ..... divide both sides by 20
n = 7
Seven friends went to do dinner, splitting a $140 bill, paying $20 each
Answer:
m/n; $80; 7*x; 7 friends
Step-by-step explanation:
(I) $x=$m/n
(II) $x=400/5=$80
(III) $m=7*x
(IV) n=140/20=7
In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent
angles FGH and FHG
Step-by-step explanation:
Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is angles FGH and FHG

1/2 of 12 = 1/4 of ?
1/3 of 90 = 2/3 of?
Answer: 1/2 of 12 = 1/4 of 24 and 1/3 of 90 = 2/3 of 45
Step-by-step explanation:
Answer:
1. 1/4 of 24
half of 12 is 6.
6+6+6+6 = 24
1/4 of 24 is 6
1/2 of 12 is 6
2. 2/3 of 45
1/3 of 90 is 30
15+15+15 = 45
so 2/3 would be 30

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites
Answer:
h = 59 hours
Step-by-step explanation:
Total earnings = fixed charge + variable charge
Fixed charge = $65
Variable charge = $15h
Where, h = number of hours
Total earnings = $950
Total earnings = fixed charge + variable charge
950 = 65 + 15h
Subtract 65 from both sides
950 - 65 = 65 + 15h - 65
885 = 15h
Divide both sides by 15
h = 885 / 15
= 59
h = 59 hours

The soccer team is selling bags of popcorn for $3 each and cups of lemonade for $2 each. To make a profit, they must collect a total of more than $120. Write an inequality to represent the number of bags of popcorn sold, p, and the number of cups of lemonade sold, c, in order to make a profit.
Answer:
3p +2c greater than 120. 120∠ 2c + 3p
Hope this helps.
An inequality to represent the number of bags of popcorn sold, p, and the number of cups of lemonade sold, c, in order to make a profit is [tex]3p + 2c > 120[/tex].
Let the number of bags of popcorn sold be p.Let the number of cups of lemonade sold be c.Given the following data:
Price of a bag of popcorn = $3Price of a bag of lemonade = $2To write an inequality to represent the number of bags of popcorn sold, p, and the number of cups of lemonade sold, c, in order to make a profit:
In order for the soccer team to make profit, the sum of the total cost of goods sold must be greater than $120.
Therefore, the mathematical expression is represented as follows:

Answer:
x=9
Step-by-step explanation:
First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.
You then come up with 13.5=1.5x
Divide both of them by 1.5 and then you get x=9
Answer:
X=9
Step-by-step explanation:
Okay first Hello! :)
so, B is the mid point of the segment midpoint means the half way
so, if AB= 5x+18 is the half to get the whole you would need to times it by 2
you get 10x+36
so now you equal them together
10x+36= 13x +9
Always move your smaller x, and now you got
3x+9=36
move your 9 over and switch the sign you get
3x=27
divide by three and you get
X=9

30 = 8x
divide both sides by 8
30/8 = 8x /8
